2Pin DO-214AA SMB Schottky Barrier Surface Mount Rectifier Diode SS24 2.0A
I Surface Mount Rectifier Diode Description
These diodes exhibit very low forward voltage drop with a very fast switching action. The reverse recovery times of Schottky diodes are extremely short and they are suitable for applications requiring fast switching and low power loss.
II Surface Mount Rectifier Diode Working of Schottky Diode
The most important physical parameter of this Schottky diode is their fast switching rate and less forward voltage drop. It is a metal – semiconductor junction that does not have the capacity to store charges at their junction. The reason behind this is due to absence of depletion layer.
Usually, a voltage drop happens across the diode terminals, when current flows through a diode. Schottky diode voltage drop is usually between 0.15 and 0.45 volts when compared to a normal diode. A normal PN junction diode has a voltage drop ranging between 0.6 to 1.7 volts. For a better efficiency and output, voltage drop should be low. When manufacturing the diode, N-type semiconductor acts as a cathode and the metal side acts an anode of the diode.
When voltage is given to the diode, the current flows in the forward direction. When this current flows through the diode, there will be a minimum voltage loss across the terminals of the diode. This loss of voltage is called as Voltage drop.
